(1) Operating voltage: 1.8V~3.6V, 3.3V recommended (2) Work in 433MHz band license-free use (3) High operating rate 500kbps, support 2-, GFSK and MSK modulation (4) Software modifiable rate parameters to better meet customer requirements under different conditions of use High rate: faster data transmission rate. Low rate: stronger anti-interference and penetration , transmission distance High sensitivity (-110dBm at 1.2Kbps, 1% packet BER) Built-in hardware error detection and -to-multipoint communication address control Low current consumption (15.6mA in , 2.4Kbps, 433MHz) Programmable control of output power up to +10dBm for all supported frequencies Wireless function, support low-power electromagnetic wave activation, wirelessly wake up the low-power sleep state of the device support for automatic channel clearance access () transmission, that is, the listening system fast frequency change synthesizer to bring the appropriate frequency hopping system Module can be software set address, software programming is very convenient Standard DIP pitch interface for embedded applications Separate 64- and TX data Actual transmission distance of 200 or more in open area (depending on environment and communication rate, etc.) Material: PCB Color as shown Package Contents: 1 x module Only the above package content, other are not included. Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
